Toyota Tundra Service Manual: Inspection

(a) Using a ruler, measure the pad lining thickness.

Standard thickness:

11.9 mm (0.469 in.)

Minimum thickness:

1.0 mm (0.0394 in.)

If the pad lining thickness is less than the minimum, replace the pad.

HINT:

Be sure to check the wear on the front disc after replacing the brake pad with a new one.

(a) Using a micrometer, measure the disc thickness.

Standard thickness:

32.0 mm (1.26 in.)

Minimum thickness:

29.0 mm (1.14 in.)

If the disc thickness is less than the minimum, replace the disc.

(b) Using a dial indicator, measure the disc runout 10 mm (0.394 in.) from the outer edge of the disc.

Maximum disc runout:

0.05 mm (0.00197 in.)

If the runout is more than the maximum, change the installation positions of the disc and axle so that the runout is as small as possible.

If the runout is more than the maximum even when the installation positions are changed, check the bearing looseness in the axial direction (See page ) and the axle hub runout (See page ).

If the bearing looseness and the axle hub runout are normal, and if the disc thickness is not within the specified range, grind the disc.

If the disc thickness is less than the minimum, replace the disc.
